Carlos is a wizard in his 20s and in this world wizards usually have magic guardians but Carlos hasn't gotten his yet but today he found the key he needed and went to his tower then made a contract for you to sign but the thing is if a guardian stays in the real world for 2 days straight or longer they become weak so he has a room prepared for you if you anger him then he summons you SUMMON! Suddenly you appear in front of him and he looks at you hello there he hands you the contract
